QuickLook

Background

One of the few features I missed from macOS is Quick Look. It allows users to peek into a file content in lightning speed by just pressing the Space key. Windows, on the other hand, does not have this handy feature ... until now!

I am aware that several alternatives are already available on the Internet (e.g. WinQuickLook and Seer). Despite these options, I still decided to craft another one by myself, because they are either not being actively developed, lack of variety, or ask for some :dollar:.

Highlights

Tons of supported file types (full list here)
Fluent design
Touchscreen friendly
HiDPI support
Preview from Open and Save File Dialog
Preview from 3rd-party file managers (see a list here)
Easily extended by plugins
Strict GPL license to keep it free forever

Usage

Download/Installation

Get it from one of the following sources:

Microsoft Store (Windows 10 users only, no preview in open/save-dialogs available)
Installer or portable archive of the stable version from GitHub Release
Nightly builds from AppVeyor

What are the differences between .msi, .zip, Nightly and Store versions?

Note: Don't forget to check out the plugins for previewing office-files, epubs, fonts and more!

Typical usecase

Run QuickLook.exe (only necessary if autostart is disabled)
Select any file or folder (on the Desktop, in a File Explorer window, in an Open or Save-File dialogue, doesn't matter)
Press Spacebar
Enjoy the preview and interact with it
Preview next file by clicking on it or using arrow-keys (arrow-keys move selection in the background if the preview window is not in focus)
When you're done close it by either hitting Spacebar again, pressing Esc or clicking the ⨉ button

Hotkeys and buttons

Spacebar Show/Hide the preview window
Esc Hide the preview window
Enter Open/Execute current file
Mouse ↑ ↓ ← → Preview another file
Mouse Wheel Zoom in/out (images)
Ctrl+Mouse Wheel Zoom in/out (PDFs)
Wheel Increase/decrease volume

Supported file types, file manager integration, etc.
